Drug Analysis

As part of the exercise, we were required to gain background knowledge of cocaine, LSD, and meth before we started the experiment. Here is the information I gathered:

Cocaine:

     Correct Chemical Name: benzoylmethylecgonine

     Correct Chemical Formula: C17H12NO4

     pH: 7.2

LSD:
     Correct Chemical Name: Lysergic Acid Diethylamide

     Correct Chemical Formula: C20H25N3O

     pH: 4

Meth:

     Correct Chemical Name: N-methyl-1-phenyl-propan-2-amine

     Correct Chemical Formula: C10H15N

     pH: 12.8

Class Activity:

Drug 4

Drug 1

For the Drug Analysis Lab, we were given 6 unknown drugs. For each we had to determine the pH and identify each as cocaine, LSD, or meth through the use of vrious reagents. Here are our results:

Drug	pH	Cocaine Reagent (turns blue)________	LSD Reagent (turns yellow	Meth Reagent
1	4	negative	negative	positive
2	9	positive	negative	negative
3	3	negative	positive	negative
4	8	positive	negative	negative
5	12	negative	negative	positive
6	4	negative	positive	negative

 This lab would be helpful in an investigation because it can further develop the profile of possible suspects; you can identify and illegal substances were used.
